“Congressman Cummings was admitted to Johns Hopkins Hospital for a bacterial infection in his knee,” the Maryland Democrat’s office said in a statement.

“Doctors drained the infection in a minor procedure today. He is resting comfortably and expects a full recovery,” the statement continued.

The news was first reported by Politico.

Cummings, the ranking member of the Oversight and Government Reform Committee, was absent from Congress for nearly three months last year, recovering from heart surgery.

Maya Rockeymoore Cummings, the congressman’s wife, suspended her campaign for Maryland governor Friday, saying in a statement it was “due to personal considerations,” The Baltimore Sun reported.

“I thank all of the people across the country who have supported my campaign and those whom I have met on the campaign trail who also fervently believe that we can and must do better for the people of Maryland,” Rockeymoore Cummings said.
